Francesco Filelfo was born in 1398 at Tolentino, in the March of Ancona. He studied grammar, rhetoric, and Latin literature at Padua, where he was appointed professor at the early age of eighteen. In 1417 he received an invitation to teach eloquence and moral philosophy at Venice. Here he remained two years, deriving much advantage from the society of Guarino da Verona and Vittorino da Feltre, and forming useful connections with the Venetian nobility. Young as he was, Filelfo had already made his mark, and won the consideration which attaches to men of decided character and extraordinary powers. The proof of this is that, after being admitted citizen of Venice by public decree, he was appointed Secretary to the Baily (_Bailo_, or Consul-General) of Constantinople through the interest of his friend Lionardo Giustiniani. Giustiniani having also provided him with money for his voyage, Filelfo set off in 1419 for the capital of Greek learning. Of the three Italian teachers--Guarino, Aurispa, and Filelfo--who made this journey for the express purpose of acquiring the Greek language and collecting Greek books, Filelfo was by far the most distinguished. The history, therefore, of his adventures may be taken as a specimen of what befell them all. The time spent at sea between Venice and Byzantium was five months; Filelfo did not arrive till the year 1420 was already well advanced. He put himself at once under the tuition of John Chrysoloras, the brother of Manuel, whose influence at the Imperial Court brought Filelfo into favour with John Palæologus. The young Italian student, having speedily acquired familiarity with the Greek tongue, received the titles of Secretary and Counsellor, and executed some important diplomatic missions for his Imperial master. We hear, for instance, of his being sent to Sigismund, the German Emperor, at Buda, and of his reciting an Epithalamial Oration at Cracow on the marriage of King Ladislaus. The Venetian Baily, again, despatched him to the Court of Amurath II., in order to negotiate terms of treaty between the Republic and the Turk. The confidence extended alike by his Venetian and Greek patrons to Filelfo may well have inclined Chrysoloras to look with favour on the affection which now sprang up between the Italian stranger and his daughter Theodora. Theodora was but fourteen years of age; yet her youth probably suggested no impediment to marriage in the semi-Oriental society of the Greek capital. That she was connected by blood with the Imperial family made the alliance honourable to Filelfo; still there is no sufficient reason to conclude for certain that the match was so unequal as to justify the malignant suggestions thrown out at a later date by Poggio.[254] Of ancient blood there was enough and to spare at Constantinople; but wealth was wanting, while the talent which rendered Filelfo serviceable to great states and empires was itself sufficient guarantee for Theodora's maintenance in a becoming station.
